Re: Please help locate where the O2 sensor that has an error of PO430.
Thanks for the response. Lexington, KY dosen't have an emissions
testing requirement. I think I am going to try the O2 sensor before
getting the emissions tested by a local garge or maby I will pay big
bucks and let ford run diags on there equiptment. The main thing that
I need to know at this point is where the sensor is located, and you
have helped me with that problem. I lucked out a couple of years ago
replacing the upstream Sensor on the passenger side. Many thanks for
the information I will put it to good use.
